Bidzilya & Yu. Budashkin Abstract Scrobipalpa halimifolia Bidzilya & Budashkin, sp. n. and S. griseoflava Bidzilya & Budashkin, sp. n. are described from the Eastern Crimea (Ukraine). Both species inhabit halophilic biotopes with Halimione verrucifera (M.B) Aellen (Chenopodiaceae), which is a host plant for S. halimifolia Bidzilya & Budashkin, sp. n. The external appearance of the adult and the genitalia of the new species and their habitats are illustrated. KEY WORD: Lepidoptera, Gelechiidae, Scrobipalpa, new species, Crimea, Ukraine.

Introduction The genus Scrobipalpa comprises about 270 species in the Palaearctic region (POVOLNY´, 2002; FALKOVITSH & BIDZILYA, 2003, 2006, 2009; BIDZILYA, 2009; BIDZILYA & LEE, 2010; HUEMER & KARSHOLT, 2010), five species in Australia (POVOLNY´, 1977), nearly 20 species in the Afrotropical region (BIDZILYA et al., 2011) and ten species in the Nearctic region (LEE et al., 2009). In Ukraine the genus Scrobipalpa is represented by about 40 species, of which 30 are known from the Crimea. As a result of many years observation of the biology and taxonomic study of Microlepidoptera in the Eastern Crimea by the second author, a long series of Scrobipalpa-species, restricted to halophilic habitats with Halimione verrucifera as a dominant plant, were collected. A recently published revision of European Gnorimoschemini (HUEMER & KARSHOLT, 2010) give us an opportunity to clearly identify all Scrobipalpa species, occurring in these habitats, two of which are described here as new. The type material is deposited in the Zoological Museum, Kiev National Taras Shevchenko University. The terminology of the genitalia follows HUEMER & KARSHOLT (2010).

Description (Figs. 1-5): Wingspan 13.2-14.0 mm. Head and thorax covered with grey, brown-tipped scales, frons light-grey to whitish, tegulae grey, mixed with light-brown; labial palpus strongly up-curved, segment 2 grey mottled with brown, with brush of short scales underside; segment 3 narrow, acute, brown with narrow light grey medial and apical rings; proboscis light grey. Scapus brown, other antennal segments brown with narrow grey rings at base. Forewing covered mainly with light grey, brown-tipped scales, costal margin, apex and termen darker, nearly blackish, veins and area along dorsum distinctly mottled with orange-brown. Brown subcostal spot at 1/4 and three dark spots in cell well developed. Fringe grey, brown-tipped. Hindwing and its fringe light grey. Variation: Some specimens with strongly developed orange-brown scales along veins and reduced black subapical streak and dark spots in cell (Fig. 3); in other cases, orange-brown pattern nearly reduced, but dark spots in cell surrounded by orange and additional two-three black points well expressed in basal 1/4 (Figs. 4-5). Male genitalia (Fig. 15): Tegumen narrow, prolonged. Uncus twice longer than broad, posterior margin with distinct medial depression. Gnathos short, narrow, weakly curved. Valva narrow, apical 1/4 broadly rounded, nearly exceeds the top of uncus. Sacculus about 1/4 length of valva, weakly curved inwards, outer margin strongly curved, with pointed tips. Vincular processes short, very narrow, curved outwardly towards tips of sacculus, separated by deep and broad medial incision. Tegumen moderately broad. Saccus gradually narrowed apically. Aedeagus straight, nearly as long as the length of tegumen, basal portion weakly swollen, slightly broader than distal portion, apical cornutus distinct, weakly curved basally. Variation: Saccus slightly varies in width. Female genitalia (Figs. 17-18): Papilla analis suboval, sparsely covered with short setae. Apophyses anteriores moderately broad, about as long as the length of segment VIII, straight, five times shorter, than apophyses posteriores. Segment VIII about as long as broad, subgenital plates narrow, broadly separated, with small foamy sclerotized patterns at anterior-medial corner. Subostial lobes broad, rounded apically, not exceeding proximal margin of segment VIII, entirely covered with microtrichia, separated by deep triangular incision. Ductus bursae moderately broad, colliculum narrow, ring-shaped. Corpus bursae rounded, signum long, weakly curved, horn-shaped, with short teeth basally, placed at the right side of the entrance of bursae copulatrix. Variation: The teeth at the base of signum vary in length; signum from weakly curved to nearly straight. Diagnosis: S. halimifolia Bidzilya & Budashkin, sp. n., externally resembles S. artemisiella (Treitschke, 1833) and S. pauperella (Heinemann, 1870) having light-brown forewing with dark blackish veins and sometimes with dark spots in cell. The new species resembles S. hendrikseni Huemer & Karsholt, 2010 and S. golovushkini Bidzilya, 2009 in the male genitalia, having narrow and straight vincular processes separated by broad medial emargination on the posterior margin of vinculum. It differs from both species in curved inwards sacculus and shorter valvae, which do not exceed the posterior margin of uncus; the new species may be separated additionally from S. hendrikseni by the shorter aedeagus, and from S. golovushkini by the nearly sub- rectangular rather than apically narrowed uncus. The new species also resembles S. subnitens Povolny´, 1969 from Mongolia, but can be recognized by longer valvae and narrower uncus. The female genitalia of new species are most similar to those of S. pulchra Povolny´, 1967 and S. clintoni Povolny´, 1968, but differ from the first species in distinctly separated subostial lobes and from the later species in strongly foamy sculptured subgenital plates and smaller basal plate of signum. Bionomy: The larva mines the leaves of Halimione verrucifera (Figs. 13-14). In the type locality larvae are observed annually from the second decade of May to the first decade of June. The larvae live in large spot-like mines on the leaves of host plant. Usually the larvae change several mines during their life. Pupation takes place 390 SHILAP Revta. lepid., 39 (156), diciembre 2011 389-396 Two new species of the 3/1/12 10:56 Página 391 TWO NEW SPECIES OF THE GENUS SCROBIPALPA JANSE, 1951 FROM THE EASTERN CRIMEA outside of the larval habitation (in plant litter or in the upper layer of ground) in a light whitish cocoon. The pupal stage continues for nearly two weeks without diapause. The adults were observed from the end of May to early September in Halimione habitats (Figs. 9-12), probably in 2-3 generations. All specimens were collected in the evening before sunset. Distribution: Eastern Crimea (Ukraine). Etymology: The specific name is derived from the Latin folium - leaf, referring to the feeding of larva on the leaves of Halimione. Scrobipalpa griseoflava Bidzilya & Budashkin, sp. n. Type material.
